The images show detailed anatomical views of a horse's forelimb, focusing on the muscular structure. **Top Image:**- This side view highlights the forelimb anatomy, emphasizing the flexor muscles. The muscles are illustrated in purple against the bone structure, which is depicted in a neutral tone. This visual helps in understanding the location and orientation of the muscles relative to the bone.**Bottom Image:**- This view appears to display the forelimb from a slightly different angle, again showcasing the flexor muscle group in purple. The emphasis is on the intricate connections between the muscles and the underlying skeletal structure.These diagrams are educational and serve as a reference for students or anyone interested in equine anatomy, especially in understanding how muscles are positioned in relation to bones in movement mechanics. **Question 15**Identify the **origin** of the highlighted muscle:[Two images of a lower leg are shown, highlighting a muscle in purple on the posterior and lateral views]Options:- A: Head and shaft of Fibula and Posterior surface of Tibia- B: Lateral condyle of Tibia- C: Pubis- D: Lateral condyle of Tibia- E: Ischial Tuberosity- F: Lateral and Medial Condyles of Femur- G: Anterior Inferior Iliac spine**Images Explanation:**The images feature two views of a lower leg, showcasing a muscle highlighted in purple. The first image provides a lateral view where the muscle runs along the side of the leg. The second image displays a posterior view, offering a perspective of the muscle from the back of the leg. These visuals assist in identifying the origin of the muscle from the given anatomical landmarks.

Legs generally have long muscles. The muscles in the leg are highly stretchable. The contraction and relaxation of these long muscles bring movement in the skeletal bones and overall movement of the body. Smaller muscles along with the larger muscles stabilize the joints.The highlighted part of this image is showing a long muscle which is present in the lateral part of the front leg. It works to extend the foot at the ankle along with the four small toes. This lateral long muscle is called the "Extensor digitorum Longus muscle". This muscle originates from the lateral tibial condyle. It is the upper portion of the tibia. Option A is incorrect because the muscles of the biceps originate from the head of the fibula and the posterior surface of the tibia is the site of origin of soleus muscles.Option C is incorrect Because Pubis forms the hip bone.Option E is incorrect because all the muscles in the posterior compartment of the thighs originate from the ischial tuberosity.Option F is incorrect because the lateral and medial condyle of the femur articulates with the lateral and medial condyle of the tibia.Option G is incorrect because the anterior inferior iliac spine is the upper part of the pelvis.Hence, the highlighted muscle is the Extensor digitorum longus muscle that originates from the tibia's lateral condyle. So, the correct answer is both a and d because both the options are the same
